Password in auth-detail file

Hi everyone, I am using Freeradius with LDAP. I use EAP-TTLS for authentication with PAP (the passwords in LDAP being crypted). In the ldap.conf file I have : log_auth_badpass = no log_auth_goopass = no But I still see the user password in clear text in the auth-detail file. I am sorry if this is a silly question but I have been trying to find a solution for quite a while now and still haven't found anything. Is it possible to make sure the passwords are not stored in the auth- detail files? Or does it have to be like this? Thank you all in advance.
